To all ic/0m t may concern.'

Be it known that I, J osEPi-r Himscn, a citizen of the United States, and a resident of the city of Milwaukee and State of Wis.- consin, have invented certain new and use ful Improvements in a Nap-Brushing Machine; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which formV a ypart of this specification.

This invention relates to nap brushing machines' especially adapted for brushing and strlightening` up the nap of blankets andthe like after 4they :have been washed. i

`One of the principal objects. of the invention is tov provide improved means for feed-ing a blanket through the-machine.

Another object `of the invention is to pro- -vide improved means for collecting the lint,

etc., removed during the brushing operation. A further object of the invention is to provide improved controlling and operating'. means for nap brushing machines.

.Other and lfurther important objects of this invention will be apparent from the disclosures vin the drawings and accompanying specification.

The invention (in a preferred form) is drawings and hereinafter more f u'lly described.

On Ythe drawings:

Figure 1 is a front elevation of a machine embodying the present invention.

Figure `2 is a section on the line 2-2 of Figure 1.

Figure 3 is a section on the line 3 3 of igure l.

Figure 4 is a section on the line 4-4 of Figure 3.

Figure `5 is a -detail view showing the carded surface of one ofthe feed rolls.

'Figure `6 is 'a detail view showing a pait O f the brush.

As, shown on the drawings:

vThe machine comprises 'a pair ofstandards 10 connected at their lrear by a flanged beam 11, and adjacent the front by a beam 12.

'Between the standards is arranged a feed plate 13, over which the blanket passes from the forward compartment of a receptacle ,118 to a pairof feed rolls @14 and 15. The blanket passes around the feed roll 14 downwardly and forwardly over a guide Serial No. 683,607.

plate 1.6. I n its passage over the roll 14 is engaged by the rotating brush up and straighten its nap. The

partment of the receptacle 18. By dividing the receptacle into two compartments there is no possibility of one blanket catching on another and drawing the latter with it through the machine. This receptacle is supported by hooks 19 and 20 which rcleas ably engage pins 21 and 22 respectively.

Over the brush 17 is arranged a hood 24 which is extended downwards at its rear to the intake of an exhaust fan 25. The guide plate lo is also extended up and around a supporting tube 26 to form the other part of such intake. This fan is adapted to withdraw any lint or other material removed by the brush 17, and to discharge it through opening 2.7 into a bag or other collect-ing means not shown.

The machine is driven by means of a shaft 28 journaled in the standards l0 and `driven from any suitable `source of power" (not shown). The impeller 29 of the suction fan is directly mounted on this shaft. Y

The shaft 28 carries al sprocket 30 for engagement with a `chain "3l, which passies around a sprocket '32 on tli'eshaftSS which carries the jbrush 1:7 n this shaft 33 is a second sprocket (not shown) for driving a shaft 34jby means of chain 35 and sprocket 36.

The lower feed roll 14 is mounted on a shaft 37 journaled in a pair of frames 38 pivotally supported lby the shaft 34. This construction allows of up and down movement Yof the shaft 37 without interfering with `the internieshing of the gear 39 and pinion 40 by means of which Vthe shaft 37 is driven from the shaft 34.

The upper feed roll 15 is journaled in a pair of frames 75 pivotally supported by the shaft 33 and is driven from the shaft 37 by means of gears 41 and 42. As the roll 1 5 is free to rise and fall with the roll 14, thegears 41 and 42 are always in mesh.

The pinion 40 is rotatably `mounted upon its shaft, but iS adapted to be operatively connected thereto by means of a slidable clutch member 43. This clutch member .is moved into and out ofengagement by a lever 44 pivotallymou'nted at 45 on a bracket 46 secured to thestanddard.

ing the clutch.

. The frames 38 which carry the lower feed roll 14 are as above stated, oscillatable about the shaft 34. One of these frames is connected to the member 49 by means of links 54 and 55. These links are slidably connected together, springs 56 and 57 being provided for the purpose of resiliently holding the links in a definite position with respect to each other. With this construction, movement of thehand lever 47 transversely of the machine causes the feed roll 14 to be raised and lowered. Y

The hand lever 47 extends through an L-shaped slot 68 in the standard 10 so that the operations of raising or lowering the feed roll 14 and operating the clutch are performed successively and cannot be performed simultaneously.

The range of upward movement of the roll 14 may be controlled by an adjustable stop member 69 arranged in the plane of movement of the hand lever 47 and pivotally mounted at on the standard 10. A rod 71 extending through an aperture in the standardv 's pivotally connected to the upper end of the member 69. This rod is notched on its under side for engagement with the edge of the aperture through which it passes. By this means the position of the stop membermay be, adjusted to limit the extent of movement of the hand-lever to any desired amount.

The feed roll 14 sometimes called a pricker 'roll is preferably provided with an inclined wire surface, constructed, as shown in Figure 5, of a sheet of leather 58 with a series of wire staples 59 passed obliquely therethrough with the ends sharpened and projecting. These ends lare arranged to project in the opposite direction to the direction of movement of the feed roll so as to allow the blanket as it leaves the latter to slip off these projecting ends.

As the brush is moving in the same direction as, although much faster than the blanket, the tendency of the brush 17 is to force the blanket firmly into engagement with the projections on the roll 14.

It will be observed that the blanket travels down the guide plate 16 with its unbrushed side uppermost and is deposited in that position in the receptacle 18 so that it is posi- 'tioned for re-insertion in the machine for brushing its other side.

The separation of the blanket from the pricker roll 14 is ensured by a series of cords 6() which pass around grooves in the roll 14, and a pair of grooved spacing rolls 61 and 62 journalled at their ends in the standard 10.

The other feed roll 15 may conveniently be provided with a resilient surface of rubber or the like.

The brush 17 may be formed as shown in Figure 6 of a strip 63 of rubber, cloth or combinationof rubber and cloth with a series of bristles 64 inserted therein.

Separation of the blanket from the brush 17 is ensured by strippers 65 mounted on the guard plate 16. For positively pushing the edge of the blanket downwards between the cords 60 and the guard plate 16, a series of brushes 66 are mounted on the shaft 34.

The operation is as follows:

The motor or other means for driving the shaft 28 is placed in operation with the hand lever 47 in the position shown in Figure 1. With the lever in this positionthe clutch 43 is disconnected so that the feed or pricker roll 14 is stationary. The latter is also lowered out of engagement with the brush 17.

The edge of the blanket is then passed over the feed plate 13 until it is picked up by the cords 60 and carried into the nip between the feed rolls 14 and 15.

I am aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise that necessitated by the prior art.

I claim as my invention:

1. A nap brushing machine comprising a pair of feed rolls, one of said rolls having an inclined wire surface and the other of said rolls a resilient surface, a rotating brush adapted to engage a blanket as it passes over the inclined wire surface, the projections on said inclined wire surface extending in the opposite direction to the movement of said surface.

2. A nap brushing machine comprising a pair of cooperating feed rolls, one of said rolls having an inclined wire surface, a rotating brush adapted to engage a blanket as it passes over the inclined wire surface, the projections on said inclined wire surface extending in opposite directions to the movement of said surface.
